I am fascinated by the consequence of sexual selection, i.e., how organisms reproduce. Currently, I focus on reproductive strategies of simultaneous hermaphrodites because of their uniqueness, compared with that of separate-sexed species. For example, simultaneous hermaphrodites choose to act as male or female upon copulation, or they potentially can manipulate the male function of female-acting partners. I am carrying out trait-based experiments, using genetic / behavioural / physiological approaches in the great pond snail, Lymnaea stagnalis.
